This exact same thing was happening to me too with my KT6 Delta.

Sure. The problem is almost certainly to do with interrupt sharing. In
my case it was a problem with the ACPI steering assigning too many
devices the same IRQ. I ended up fixing it by disabling unnecessary
onboard hardware (eg I don't need 8 USB controllers or onboard sound),
using acpi=off (is that different to your acpi=no ?) and re-positioning
According to proc/interrupts, there shouldn't be a sharing problem. However, I'm unsure if there is a difference between acpi=no and acpi=off. I'll try "off" and see if I can pound away on the NIC and the hard drive and see what happens.
